Abstract: The present invention provides matrixes doped with semiconductor nanocrystals. In certain embodiments, the semiconductor nanocrystals have a size and composition such that they absorb or emit light at particular wavelengths. The nanocrystals can comprise ligands that allow for mixing with various matrix materials, including polymers, such that a minimal portion of light is scattered by the matrixes. The matrixes of the present invention can also be utilized in refractive index matching applications. In other embodiments, semiconductor nanocrystals are embedded within matrixes to form a nanocrystal density gradient, thereby creating an effective refractive index gradient. The matrixes of the present invention can also be used as filters and antireflective coatings on optical devices and as down-converting layers. The present invention also provides processes for producing matrixes comprising semiconductor nanocrystals.

Abstract: A retroreflective laminate sheeting has a viewing surface having a retroreflective layer which has a first cap-Y value of a viewing surface side thereof. A plurality of discrete pigmented indicia are disposed on the viewing surface side of the retroreflective layer. The pigmented indicia define a second cap-Y value of the viewing surface of the sheeting, the second cap-Y value being less than the first cap-Y value. One method of making a retroreflective sheeting includes forming a retroreflective layer on a web, the web moving in a web direction. The method includes applying a pigmented material proximate the retroreflective layer, the pigmented material preferably forming a plurality of parallel stripes oriented substantially in at least one of the web direction and a direction orthogonal to the web direction.

Abstract: A system comprising a linerless pressure sensitive label stock and a printer for printing on linerless pressure sensitive label stock exhibit reduced tendency for exposed adhesive to stick to printer components. The linerless pressure sensitive label stock has a plurality of regions that are substantially non-tacky formed along the length of the label stock web. In one embodiment, the non-tacky regions are formed by printing an adhesive deadening agent over the pressure sensitive adhesive. In another embodiment, the adhesive is printed in a pattern having non-tacky regions. Optional perforations in the non-tacky regions aid separation of printed regions from the rest of the web. Various means of web position sensing allow the printer to track the positions of the substantially non-tacky regions. After printing, the web of linerless pressure sensitive label stock is moved to positions where it is unlikely to stick to printer components.

Abstract: Clear and opaque polymeric film structures for providing clear and opaque labels that are removable, respectively. The film structure includes a core layer and first skin layer, wherein the first skin layer contains a polymeric matrix of a material that allows a label, which has been produced from the film structure and applied onto a container or product, to be removed from the container or product by the solution employed in a process for re-using the container. The first skin layer is co-extruded along with the remainder of the layers of the film structure, or the first skin layer is deposited on the film structure as an emulsion or extrusion coating. The first skin layer can be contacted with a water-based adhesive to affix the label onto a particular product or product container. Labels produced from the film structure exhibit a desirable combination of excellent initial adhesion strength, moisture resistance and delaminatability, as well as excellent removability.
